Definitions
- This invention relates to an underground, contained pipe assembly, the components of which are readily removable after installation for repair and maintenance.
- Underground tank systems are defined as any system that has 10% or more of its overall volume underground, including associated piping.
- Such systems are regulated by legislation which require the use of secondary containment with interstitial monitoring for systems that contain or transport hazardous chemicals or substances.
- the provision of secondary containment is optional for systems that carry or transport oil, gasoline or other petroleum based products, but in any case, the use of corrosion resistant materials is mandatory for new systems.
- the concept of double containment piping provides the additional degree of safety for pipes that are designed to transport hazardous, toxic or extremely corrosive chemicals.
- a system capable of being readily accessible would give the facility engineer the ability to have the tank or pipe section requiring modification or repair capable of being modified without a major excavation and disruption to the business. In some instances, a faulty tank or pipe section could be sent to a shop for repair, and then readily placed back into service.
- a concrete containment tank and associated outer containment piping system is constructed in modular sections with the containment piping sections joined inside of the lined concrete containment tank.
- the secondary containment system for the section of primary piping within the tank can consist solely of the tank. Ready access to the interior of the tank and its connections is provided through a removable cover or manhole.
- a bendable primary pipe, through which fluid flows, is supported for longitudinal movement due to thermal expansion within the interior of the concrete containment tank.
- the double containment system is formed in straight sections and comprises the primary piping enclosed within a spaced, outer or double containment pipe. All of the double containment pipes are terminated inside of the lined-concrete tanks or housings. The tanks are designed to allow straight lengths of primary piping between consecutive tank locations.
- the primary piping may be extracted, removed and reinserted through a flexible pipe opening in one wall of the tank at one end and above ground at its other end or the piping may be passed into a below ground pipe if the repair can be achieved in the tank.
- the only criteria is that the straight sections of primary piping or the length of the tank would have to be long enough in order that the bending radius of the primary piping is not exceeded during the extraction, removal and reinsertion processes.
- FIGURE is a cross-sectional view of the underground containment tank and removable primary piping assembly comprising the subject matter of the present invention.
- the invention consists of a double containment piping and tank system generally indicated at 10.
- the system 10 includes a metallic, fiber reinforced, bendable thermosetting plastic or thermoplastic inner piping 12 through which the primary fluid conveyed by the system flows.
- Piping 12 is contained and housed within a thermoplastic-lined concrete encasement or tank 14 provided with a cover 16 which is removable, permitting access to the interior of tank 14. Upon removal of the cover 16, access to the primary piping 12 for repair or maintenance as required, is attained through manhole access port 18.
- thermoplastic liner 22 which is accomplished with the use of specially produced thermoplastic studded sheets described in detail in my copending application Ser. No. 07/719,840 filed June 24, 1991 and assigned to the same assignee as the present application, which disclosure is incorporated herein. Portions of the thermoplastic sheets 24 can be joined together, where needed, along a sinusoidal mechanical lock seam to prevent moisture penetration of the encasement or tank 14 and cover 16.
- Penetrations through the lined concrete of the encasement or tank 14 and cover 16, as needed, can be accomplished with the use of a mechanical seal (such as Link-Seal by Thunderline Corporation of Minnesota), by the use of water stops that are welded to the pipe and embedded in the concrete, by the use of welding the pipes directly to the sheet lining, or any combination of these.
- a mechanical seal such as Link-Seal by Thunderline Corporation of Minnesota
- the lined concrete encasement or tank 14 is also manufactured with a plurality of spaced plastic-coated steel support sections 30 having an inverted T-beam configuration.
- the supports 30 are embedded into the concrete wall of tank 14 or welded to the liner 22 if the T-beam coating is compatible.
- the support structures 30 support the primary piping 12.
- An outer containment pipe 34 outside of the access tank 14 may also be embedded in the encasement or tank concrete or secured to a compatible material sleeve 33 in the wall of tank 14 and welded to liner 22 inside of tank 14, if compatible with the tank, as shown at 35.
- Inner piping 12 and outer piping 34 terminating at tank 14 may be formed from different materials since they are not joined to each other directly but only through the concrete encasement or tank 14.
- the inner piping 12 is spaced from the walls of center piping 34 by spacers 39.
- An expansion pipe joint fitting 31 may be used to form the ends of the straight sections of primary piping 12 within tank 14, to accommodate expansion and construction of the piping 12 due to changing thermal conditions.
- a termination fitting (not shown) with an "O" ring gland seal may be inserted across the open space between the end of each pipe 34 and the outer diameter of pipe 12 to close the same and prevent leakage in tank 14 from the interior of the containment pipe 34.
- the primary piping 12 may be extracted, removed and reinserted through a flexible curved pipe 40 opening at 42 in one wall of tank 14 at one end and above ground surface S at its other end 44 provided with a threaded plug-type cap 46 to normally close the same.
- the piping 12 to be repaired may be passed through opening 42, bent, and removed through opening 44 above ground. It may be reinserted in a like manner.
- the section of primary piping 12 removed or the length of the tank 14 would have to be long enough in order that the bending radius of the primary piping is not exceeded during the extraction, removal or reinsertion processes.
- the repair may be done in the tank 14 and the end of the piping 12 inserted in a tube or second flexible curved pipe 48 having an open end 50 in one wall of tank 14 and a second capped end 52 provided with a threaded cap 54 below ground surface S.
- Flexible curved pipe 48 allows the piping to be completely extracted or at least a minimum excavation would have to be performed above opening 52. It would still be less than what would be required if an entire straight section of pipe would have to be excavated.
- a water stop or barrier 56 may be secured to each pipe 40,48 and embedded in the adjacent wall of tank 14.
- the ends 42,50 of the pipes may be welded, if compatible to the liner 22. If necessary, when reinserting or removing the piping 12 for installation in the system, the piping may be inserted first through one pipe and then the other to obtain access to an appropriate end within tank 14 which can be reattached to another straight section or removed through the above ground tube, as required.
- the pipes or tubes 40,48 may both have openings above ground surface S or below, depending on the characteristics and length of piping sections 12.
